PRIORITY

This application is a Divisional application to U.S. application Ser. No. 15/766,274, filed in the U.S. Patent and Trademark Office on Apr. 5, 2018, which is a U.S. National Phase Entry of PCT International Application No. PCT/KR2016/011131, filed on Oct. 5, 2016, which claims priority to Korean Application No. 10-2015-0139898, which was filed on Oct. 5, 2015, the content of each of which is incorporated herein by reference.

FIELD

Various embodiments disclosed herein relate to an electronic device including a display enclosing at least two sides of the electronic device and a control method therefor.

BACKGROUND

For electronic devices, such as smartphones in particular, various technologies have been developed to provide users with widescreen displays while supporting portability. Examples are wallet-shaped, rollable, or bendable terminals with flexible displays.

In addition, electronic devices having plural displays are being developed. For example, such an electronic device may have front and rear displays or may use a slanted side as a display.

When a deformable display is applied to a mobile terminal, a larger screen can be provided regardless of the physical form of the mobile terminal, but commercialization is not easy in terms of durability and cost.

To widen the display while maintaining the rectangular shape of the mobile terminal that is a popular form today, mobile terminals have been developed that have a thin bezel, have displays on the front and back sides, or have a display extended to the sides. However, in the case of a mobile terminal having displays on the front and back sides, it is difficult to use the displays at the same time. In the case of a mobile terminal having a display extended to the side, when the user holds the mobile terminal with one hand, a touch may be input to the side display, causing malfunction.

SUMMARY

Accordingly, an aspect of the present disclosure is to provide an electronic device having plural displays that permits the user gripping the electronic device to view all the displays.

In accordance with an aspect of the present disclosure, an electronic device is provided. The electronic device includes a first surface in a first direction, a second surface in a second direction opposite to the first direction, and a third surface enclosing at least a portion of a space formed between the first surface and the second surface. The electronic device also includes an audio module changing an audio signal input to the electronic device into an electronic signal, and a processor being operationally connected to the display and the audio module. The processor is configured to detect the audio signal input via the audio module from a first user via the first surface, detect a touch signal dragged from the third surface in the direction of the second surface, and display in the second surface a translation corresponding to the audio signal.

In accordance with another aspect of the present disclosure, a method is provided for controlling an electronic device equipped with a display including a first surface in a first direction, a second surface in a second direction, and a third surface enclosing at least a portion of the space formed between the first surface and the second surface. An audio signal is detected that is input via an audio module from a first user via the first surface. A touch signal is detected that is dragged from the third surface in the direction of the second surface. A translation corresponding to the audio signal is displayed in the second surface.

In a feature of the present disclosure, an electronic device is provided having plural touchscreen displays and a control method therefor. The electronic device and control method thereof can support a plurality of working screens associated with multiple applications and can detect a user's touch gesture and display corresponding information on the multiple concatenated touchscreen displays.

In another feature of the present disclosure, when the user holds the electronic device with one hand, the user can view visual information presented through the displays on the plural sides of the electronic device without interruption. By utilizing the volume between the displays, the user can be provided with an input interface producing a sense of space such as a wheel UI. It is also possible to provide a continuous UI/UX presented across multiple sides.

DETAILED DESCRIPTION

Hereinafter, various embodiments of the present disclosure are described with reference to the accompanying drawings. However, it should be appreciated that the present disclosure is not limited to a specific embodiment and all modifications, equivalents, and/or alternatives thereof also belong to the scope of the present disclosure. The same or similar reference symbols are used throughout the drawings to refer to the same or like parts.

In the description, an expression “have”, “may have”, “include” or “may include” indicates the existence of a specific feature (e.g. number, function, operation, or component like a part) and does not exclude the existence of other features.

In the description, the expression “A or B”, “at least one of A and/or B”, or “one or more of A and/or B” may indicate all possible combinations of A and B. For example, “A or B”, “at least one of A and B”, and “at least one of A or B” may indicate any of (1) including at least A, (2) including at least B, or (3) including at least A and at least B.

In various embodiments, the terms “first” and “second” may refer to various elements regardless of importance and/or order and are used to distinguish one element from another element without limitation. For example, a first user device and a second user device may indicate different user devices regardless of the order or importance of the devices. As another example, a first component may be denoted as a second component, and vice versa without departing from the scope of the present disclosure.

It will be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “coupled with/to” or “connected with/to” another element (e.g., second element), it can be coupled or connected with/to the other element directly or via a third element. In contrast, it will be understood that when an element (e.g., first element) is referred to as being “directly coupled with/to” or “directly connected with/to” another element (e.g., second element), no other element (e.g., third element) intervenes between the element and the other element.

In the description, the phrase “configured (or set) to” may be used interchangeably with the phrase “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to” or “capable of” depending on circumstances. The term “configured (or set) to” does not essentially mean “specifically designed in hardware to.” Rather, the phrase “configured to” may mean that a device can perform a specific operation together with other devices or parts. For example, the phrase “processor configured (or set) to perform A, B, and C” may mean a dedicated processor (e.g., embedded processor) for performing the operations or a general-purpose processor (e.g., central processing unit (CPU) or application processor) that may perform the operations by executing one or more software programs stored in a memory unit.

Some terms used herein may be provided merely to describe a specific embodiment without limiting the scope of another embodiment. In the description, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms including technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Wired communication may use at least one of, for example, Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), Recommended Standard 232 (RS-232), and Plain Old Telephone Service (POTS). The network 162 may be a telecommunications network, such as a computer network (e.g., local area network (LAN) or wide area network (WAN)), the Internet, or a telephone network.

The first external electronic device 102 and the second external electronic device 104 may be of a type identical to or different from that of the electronic device 101. In one embodiment, the server 106 may be a group of one or more servers. In various embodiments, all or some of the operations executed in the electronic device 101 may be executed in one or more other electronic devices (e.g., electronic devices 102 and 104 or server 106). In one embodiment, to perform a certain function or service automatically or upon request, the electronic device 101 may, instead of or in addition to executing the function or service, request external electronic devices (e.g., electronic device 102 or 104, or server 106) to execute at least some of the function. The external electronic devices (e.g., electronic device 102 or 104, or server 106) may execute the requested function or an additional function, and return the results to the electronic device 101. The electronic device 101 may further process the received results if necessary and provide the requested function or service.

FIGS. 4A to 4E depict multiple displays and antennas mounted in the displays according to various embodiments.

FIG. 4A illustrates the display of the electronic device in various embodiments. A single display panel may be processed into a display having multiple planes applicable to the electronic device disclosed herein.

In one embodiment, the display may be configured to include a first display area 410 in a first direction, a second display area 420 in a second direction opposite to the first direction, and a third display area 430 enclosing at least a portion of the space formed between the first display area 410 and the second display area 420. The display may be seen, for example, as a “U” shape or a “⊏” shape (Korean consonant) depending on the curvature of the third display area 430. That is, the third display area 430 may have a curved shape or a planar shape.

The first display area 410 and the second display area 420 may be configured to be parallel to each other, or not to be parallel within a range that they do not contact each other in another embodiment. The configuration of the display may be determined according to the shape of the outer housing of the electronic device.

FIG. 4B is a detailed view of the cross section 440 of the display. The display of the electronic device disclosed herein may be composed of a touch panel 441 for sensing touch input, shielding layers 442 and 444 serving as a ground, a metal mesh structure 443 serving as an antenna, and a display panel 445.

In one embodiment, in the display, at least one shielding layer 444 may be stacked on the display panel 445, a metal mesh antenna 443 may be placed on the shielding layer 444, at least one shielding layer 442 may be stacked on the antenna, and the display panel 445 may be placed on the shielding layer 442. The above stacking order is an example, and the stacking order may be varied according to an addition of a component or the shape of the antenna.

The shielding layers 442 and 444 can reduce jamming that may occur when the user touches the electronic device, and they can reduce the noise due to interference between the touch panel or display panel and the antenna.

The antenna may have a structure other than a metal mesh in its shape. For example, the antenna may have a radiation pattern including at least one open boundary and plural radiating portions arranged across the open boundary. The shape of the antenna can be configured to minimize noise by varying the spiral or stacking forms.

FIG. 4C shows an embodiment where at least one antenna may be included in each of the first to third display areas. A first antenna 451 may be disposed in the first display area 410, a second antenna 452 may be disposed in the second display area 420, and a third antenna 453 may be disposed in the third display area 430. The first to third antennas can operate independently of each other. The operation of each antenna can be determined according to the form in which the user grips the electronic device or the strength of a radio signal transmitted from the base station.

FIG. 4D illustrates various forms that the first to third antennas 461 to 463 can take. The first to third display areas 410 to 430 may have different shapes and sizes because their shapes and sizes are determined according to the shape of the outer housing. Various types of antennas can be disposed inside different display areas. The first antenna and the second antenna disposed respectively in the first display area 410 and the second display area 420 facing each other may be configured to face each other in consideration of interference therebetween.

The antenna may be configured to have a stick shape as indicated by indicia 451, or a spiral shape as indicated by indicia 461. The shape of the antenna may be modified in various ways by a person skilled in the art.

FIG. 4E illustrates activation of different antennas according to the usage pattern of the user. When a call is received while the electronic device is placed on the floor, all the first to third antennas 451 to 453 may be activated to receive signals from the base station. In this case, as indicated by indicia 470, since there is no nearby object that can cause noise (e.g., a user's hand), the electronic device can receive signals using all the antennas without interference.

As indicated by indicia 480, when the user grips the electronic device in the hand, noise may occur owing to the user's hand. If interference is strong when a signal is received using a specific antenna as a result of noise caused by a nearby object, the electronic device may deactivate that antenna and receive a signal using the remaining antennas.

As indicated by indicia 490, when the user brings the electronic device to the face for the call, radio interference can occur because of the contact between the electronic device and a portion of the face. In this case, the electronic device may receive a radio signal using only the third antenna 453 which is disposed at a relatively outer portion and it is less influenced by any noise.

The electronic device may select one or more of the antennas to be activated according to an external condition such as the behavior of the user using the electronic device or the place where the signal is being received, thereby reducing power consumption and improving call quality.

As indicated by indicia 1101, the preview image of the second user 1170 obtained by the camera 1130 can be displayed on the rear display 1120 in the same direction as the camera 1130. The second user 1170 acting as a target object can view the preview image on the rear display 1120.

As indicated by indicia 1102, the first user 1150, who takes a photograph of the second user 1170 using the electronic device, may view the preview image 1110 of the target object through the front display 1110 provided in the direction opposite to the direction in which the camera 1130 is mounted.

FIG. 12 illustrates an example of simultaneous interpretation using the electronic device according to various embodiments. In one embodiment, for the electronic device having multiple displays, the front display 1210 and the rear display 1220 may be provided.

As indicated by indicia 1201, the rear display 1220 of the electronic device is located in the direction in which the second user 1270 is looking, and translation results for what the first user 1250 speaks may be displayed on the rear display 1220. In one embodiment, after the first user 1250 speaks, when a finger or the like touches the display located on the upper side of the electronic device and moves toward the rear display 1220 (drag action) at which the second user 1270 is looking, translation results for what the first user 1250 speaks may be displayed on the rear display 1220.

Likewise, as indicated by indicia 1202, when the first user 1250 speaks to the second user 1270 in her or his native language while looking at the front display 1210, what the first user 1250 speaks may be translated into the preset language and the translation results may be displayed on the rear display 1220 at which the second user 1270 is looking.

The above example may proceed in the opposite direction. When the second user 1270 speaks to the first user 1250 while looking at the rear display 1220, what the second user 1270 speaks may be translated and the translation results may be displayed on the front display 1210 at which the first user 1250 is looking.

FIG. 13 illustrates a result of a drag action applied to the electronic device according to various embodiments. In one embodiment, for the electronic device having multiple displays, the front display 1310 may extend along the upper portion 1330 of the electronic device to the rear side 1320. The display area 1330 provided at the upper portion of the electronic device may display information on a missed call or a received message and may serve as a notification bar.

For example, when a log of a missed call is displayed on the display area 1330 provided at the upper portion, the user may touch the displayed log and drag it in the direction of the front display 1310 to make a call to the caller of the missed call. When the user touches the displayed log and drags it in the direction of the front display 1310, an application may be executed to send a message to the caller of the missed call.

Such a drag action is normally performed while the display is being touched. However, when a proximity sensor such as a hovering sensor is mounted in the electronic device, the drag operation can be activated even if only a drag gesture is performed without direct contact with the display. The function of executing the call function or message application in the above example may be replaced with a different function according to user settings.

The above drag action is merely an example of operating the electronic device disclosed herein. The action of shaking the electronic device in one direction or turning over the notebook page while holding the electronic device may be used.

FIG. 14 illustrates an action for checking all the multi-plane displays of the electronic device while the user grips the electronic device according to various embodiments. In one embodiment, when multitasking is performed in the electronic device having multiple displays, information on the tasks can be simultaneously presented on the plural displays provided in the electronic device.

As indicated by indicia 1401, while a first task is being executed using the front display 1410 provided in the electronic device, the user can initiate a second task by executing another application. In this case, the electronic device can display the newly executed second task through the rear display 1420 without terminating the first task being executed using the front display 1410. The user can simultaneously execute plural tasks while holding the electronic device.

The front display 1410 and the rear display 1420 may be independently operated for multitasking. The rear display 1420 may also serve as an auxiliary display of the front display 1410. For example, the rear display 1410 may display a folder associated with the program running on the front display 1410. In various embodiments, it is possible to provide a shortcut user interface (UI) in the form of an index through the rear display 1410.

FIG. 15 illustrates a display installed in the upper side of the electronic device according to various embodiments. In one embodiment, for the electronic device having multiple displays, the front display 1510 may extend along the upper side 1530 of the electronic device to the rear side 1520.

The display 1530 provided on the upper side of the electronic device may be implemented in a curved shape or plane shape depending on the curvature. The upper-side display 1530 may be used to display data such as messages and weather information, and may serve as a notification bar. The user can check the data through the upper-side display 1530 without taking the electronic device completely out of the pocket.

The upper-side display 1530 may provide a spatial sensation like a wheel UI and may be used as an input means for the electronic device.

FIG. 16 is a flowchart for executing a camera function of the electronic device according to various embodiments. In one embodiment, the electronic device having multi-plane displays may start capturing images when the camera provided on at least one of the displays is driven. After starting image capturing at operation 1610, the electronic device may identify the shooting mode of the user. For example, at operation 1620, the electronic device may determine whether the user wants to take a self-portrait photograph (selfie). If the self-portrait mode is selected, the controller of the electronic device may activate the rear display provided in the same direction as the direction in which the camera is mounted. At operation 1660, the preview image thus generated may be displayed on the activated rear display.

At operation 1630, the composite mode other than the self-portrait mode may be selected. In the composite mode (dual mode), both the front display and the rear display of the electronic device are activated and the preview image obtained by the camera is displayed on both of the activated displays. The composite mode may be used when two or more users take a photograph while the electronic device is being placed between the users. For example, when the first user takes a photograph of the second user, the camera of the electronic device is positioned to face the second user. In this case, the second user can view his or her current appearance in real time through the rear display provided in the same direction as the direction in which the camera is mounted. At the same time, the first user may view the captured image through the front display provided in the direction opposite to the direction in which the camera is mounted.

If the composite mode is selected at operation 1630, at operation 1640, the preview image generated may be displayed through the front display and the rear display of the electronic device. If neither the self-portrait mode nor the composite mode is selected at operation 1620 or 1630, the regular shooting mode may be selected. In the regular shooting mode, the preview image may be displayed on the front display only.

After checking the preview image, at operation 1670, the controller of the electronic device may take a photograph in response to a shooting request from the user, and generate and store the corresponding image.

Here, the front side refers to the side or face on which the main display mostly used by the user is located, and it may be the side or face on which a physical button such as the home button is usually located. In one embodiment, the front side and the rear side may be distinguished according to, but not limited to, the presence of a physical button or the location where the camera is mounted.

Also, in embodiments shown in the drawings, the front side may correspond to, but not limited to, the side on which the camera is not exposed.

FIG. 17 is a flowchart for operating the displays of the electronic device disclosed herein.

In one embodiment, after the touchscreen of the electronic device is activated, at operation 1720, the electronic device may determine whether a palm touch signal (or regular signal) is detected through the installed sensors. A palm touch signal may generally be sensed when the user grips the electronic device by hand, or it may be sensed when an input is received through a specific object such as a touch pen. A palm touch signal can be sensed through the sensors when a specific portion of the electronic device is being continuously touched.

If a palm touch signal is detected, at operation 1730, the electronic device may determine whether the palm touch signal has been sensed in the front side or in the rear side. Based on the result of the determination, the display facing the palm may be not activated and the other display facing away from the palm-facing display may be activated. This is because the display facing the palm may be not used when the user is holding the electronic device.

For example, to use the front display of the electronic device, the user may hold the electronic device so that the rear side of the electronic device is supported by the palm of the hand. Here, a palm touch signal can be detected in the direction of the rear display. On the other hand, when the user grips the electronic device to use the rear display, a palm touch signal may be detected in the direction of the front display.

Depending on the palm touch direction sensed at operation 1730, the electronic device may deactivate the front display at operation 1770 or may deactivate the rear display at operation 1780.

If no palm touch signal is detected at operation 1720, the electronic device may measure the plane tilt thereof and select the display to be activated. Here, when the display surface of the electronic device is represented by an X-Y plane, the plane tilt may refer to the angle between the Z-axis perpendicular to the X-Y plane and the ground surface. When the electronic device is placed on the ground with the front display facing up, the plane tilt of the electronic device is 90 degrees. Hence, when the plane tilt is 0 (zero), this indicates that the surface of the display of the electronic device is perpendicular to the ground surface.

Upon determining that the measured plane tilt is zero at operation 1740, the electronic device may activate the display corresponding to the direction in which user touch input is detected. On the other hand, when the plane tilt is nonzero, this may indicate that one of the front display and the rear display of the electronic device faces upward.

Upon determining that the measured plane tilt has a positive value at operation 1750, it may be determined that the front display of the electronic device faces the direction opposite to the ground. In this case, at operation 1780, the electronic device may deactivate the rear display.

Upon determining that the measured plane tilt has a negative value at operation 1750, it may be determined that the front display of the electronic device faces the ground. In this case, at operation 1770, the electronic device may deactivate the front display.

FIG. 18 is a flowchart for changing the direction of the displayed screen in response to a direction change of the electronic device disclosed herein.

In one embodiment, when the user changes the orientation of the electronic device, at operation 1820, the electronic device may determine if the rotation tilt exceeds a preset threshold. Here, when the display surface of the electronic device is represented by an X-Y plane and one of the X-axis and the Y-axis is defined as the reference axis, the rotation tilt indicates the degree of rotation of the reference axis.

Upon determining that the rotation tilt exceeds the threshold, at operation 1830, the electronic device may determine whether the direction of the palm touch signal has changed. Upon determining that the direction of the palm touch signal has changed also, at operation 1840, the electronic device may change the orientation of the screen displayed on the display.

For example, while the user is executing a first task through the front display of the electronic device, the user can reverse the electronic device to check a second task executed through the rear display. When the reversing action is detected, the rotation tilt may exceed the threshold. In that case, the electronic device may determine whether the direction of the palm touch signal has changed at operation 1830. If the user holds the electronic device in the same way while reversing the electronic device, as it can be determined that the direction of the palm touch signal is not changed, at operation 1850, the orientation of the screen displayed on the display may be maintained.

Upon determining that the rotation tilt does not exceed the threshold, at operation 1850, the electronic device may maintain the current orientation of the screen displayed on the display.
